Open Source PHP HTTP Clients

Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and trivial to integrate with web services. Simple interface for building query strings, POST requests, streaming large uploads, streaming large downloads, using HTTP cookies, uploading JSON data, etc... Can send both synchronous and asynchronous requests using the same interface. Uses PSR-7 interfaces for requests, responses, and streams. This allows you to utilize other PSR-7 compatible libraries with Guzzle. Abstracts away the underlying HTTP transport, allowing you to write environment and transport agnostic code; i.e., no hard dependency on cURL, PHP streams, sockets, or non-blocking event loops. Middleware system allows you to augment and compose client behavior.

Provides powerful methods to fetch HTTP resources synchronously or asynchronously. The HttpClient component is a low-level HTTP client with support for both PHP stream wrappers and cURL. It provides utilities to consume APIs and supports synchronous and asynchronous operations. The HTTP client contains many options you might need to take full control of the way the request is performed, including DNS pre-resolution, SSL parameters, public key pinning, etc. They can be defined globally in the configuration (to apply it to all requests) and to each request (which overrides any global configuration). It's common that some of the HTTP client options depend on the URL of the request (e.g. you must set some headers when making requests to GitHub API but not for other hosts). If that's your case, the component provides scoped clients (using ScopingHttpClient) to autoconfigure the HTTP client based on the requested URL.

Requests is a HTTP library written in PHP, for human beings. It is roughly based on the API from the excellent Requests Python library. Requests is ISC Licensed (similar to the new BSD license) and has no dependencies, except for PHP 5.6+. Despite PHP’s use as a language for the web, its tools for sending HTTP requests are severely lacking. cURL has an interesting API, to say the least, and you can’t always rely on it being available. Sockets provide only low-level access and require you to build most of the HTTP response parsing yourself. Requests allows you to send HEAD, GET, POST, PUT, DELETE, and PATCH HTTP requests. You can add headers, form data, multipart files, and parameters with basic arrays, and access the response data in the same way. Requests uses cURL and fsockopen, depending on what your system has available, but abstracts all the nasty stuff out of your way, providing a consistent API.

This package provides an asynchronous HTTP client for PHP based on Amp. Its API simplifies standards-compliant HTTP resource traversal and RESTful web service consumption without obscuring the underlying protocol. The library manually implements HTTP over TCP sockets; as such it has no dependency on ext/curl. Streams entity bodies for memory management with large transfers. Supports all standard and custom HTTP method verbs. Simplifies HTTP form submissions. Implements secure-by-default TLS. Supports cookies and sessions. Functions seamlessly behind HTTP proxies. Additionally, you might want to install the nghttp2 library to take advantage of FFI to speed up and reduce the memory usage on PHP 7.4. More extensive code examples reside in the examples directory.

klein.php is a fast & flexible router for PHP 5.3+. Flexible regular expression routing (inspired by Sinatra) A set of boilerplate methods for rapidly building web apps. Almost no overhead. Unit tests are a crucial part of developing a routing engine such as Klein. Added features or bug-fixes can have adverse effects that are hard to find without a lot of testing, hence the importance of unit testing. This project uses PHPUnit as its unit testing framework.

A webhook is a mechanism where an application can notify another application that something has happened. Technically, the application sends an HTTP request to that other application. In this blog post, I'd like to introduce you to two packages that we recently released. The first is laravel-webhook-server, which allows you to send webhook requests. The second one is laravel-webhook-client, which makes it easy to receive those webhook request. Webhooks are very useful when a system wants to be notified as soon as something happens in another system. Let's make that a bit less abstract and take a look at a real-world example. laravel-webhook-server allows you to configure and send webhooks in a Laravel app easily. So you'll install this into the app that wants to notify other apps that something has happened. The package has support for signing calls, retrying calls, and backoff strategies.

This project has two parts. The first one is a hidden counter (using the 1x1 transparent pixel GIF) which registers into a MySQL database all remote IP addresses (whether IPv4 or IPv6), it tries very hard to use IPv6. The second part shows stats.

Implementation of PSR-17 (HTTP Message Factories) This repository holds all interfaces related to PSR-17 (HTTP Factories). Note that this is not a HTTP Factory implementation of its own. It is merely interfaces that describe the components of a HTTP Factory. The installable package and implementations are listed on Packagist. PSR-7 did not include a recommendation on how to create HTTP objects, which leads to difficulties when needing to create new HTTP objects within components that are not tied to a specific implementation of PSR-7. An HTTP factory is a method by which a new HTTP object, as defined by PSR-7, is created. HTTP factories MUST implement these interfaces for each object type that is provided by the package.

HTTPlug allows you to write reusable libraries that need an HTTP client without binding to a specific implementation. We provide adapters for existing HTTP Clients, so you can use your regular tools, even in compatible third-party packages. Furthermore, you can implement your own, if you would like to. Need to log each request? Authenticate a request? It's easy. Our powerful plugin system allows you to add custom logic to the request's lifecycle. This package also provides a synchronous HttpClient interface with the same method signature as the PSR-18 client. For synchronous requests, we recommend using PSR-18 directly.

LaravelS is an out-of-the-box adapter between Laravel/Lumen and Swoole. LaravelS uses Swoole's Synchronous IO mode, the larger the worker_num setting, the better the concurrency performance, but it will cause more memory usage and process switching overhead. If one request takes 100ms, in order to provide 1000QPS concurrency, at least 100 Worker processes need to be configured. Create WebSocket Handler class, and implement interface WebSocketHandlerInterface. The instant is automatically instantiated when start, you do not need to manually create it.

Natrix is a HTTP client for PHP. Object-oriented, extensible and modular.

The original intent was to make a pretty simple "connect and send" http client, it has since grown to include as much http 1.0 client capabilitlies (as defined in RFC 1945) as possible.

ReactPHP is a low-level library for event-driven programming in PHP. At its core is an event loop, on top of which it provides low-level utilities, such as: Streams abstraction, async DNS resolver, network client/server, HTTP client/server and interaction with processes. Third-party libraries can use these components to create async network clients/servers and more. ReactPHP is production ready and battle-tested with millions of installations from all kinds of projects around the world. Its event-driven architecture makes it a perfect fit for efficient network servers and clients handling hundreds or thousands of concurrent connections, long-running applications and many other forms of cooperative multitasking with non-blocking I/O operations. What makes ReactPHP special is its vivid ecosystem with hundreds of third-party libraries allowing you to integrate with many existing systems, such as common network services, database systems and other third-party APIs.

The WebLink component manages links between resources. It is particularly useful to advise clients to preload and prefetch documents through HTTP and HTTP/2 pushes. This component implements the HTML5's Links, Preload and Resource Hints W3C's specifications. It can also be used with extensions defined in the HTML5 link type extensions wiki.
